The UGREEN X512 20W GaN Charger is in stock at Mascom International, priced at KSh 1,400, brand new and sealed with a UK 3-pin plug that fits Kenyan wall sockets. It has one USB-C port rated at 20W and supports USB Power Delivery 3.0, Quick Charge 4.0+, Huawei FCP and SCP. GaN stands for gallium nitride, a chip material that wastes less energy as heat than older silicon, so the UGREEN X512 20W GaN Charger stays small enough for a shirt pocket. You can collect it from our shop on the first floor of Old Mutual Building, Kimathi Street, Nairobi CBD.
Built for university students, sales teams and anyone who charges a phone at a desk, the UGREEN X512 20W GaN Charger replaces the slow 5W cubes that still sit in many Kenyan homes. A flat phone on one of those blocks can need most of an evening to refill. With 20W of USB-C Power Delivery, your phone gets back to a usable level over a lunch break or a long matatu wait at the stage. The UGREEN X512 20W GaN Charger also accepts any input from 100V to 240V, so it runs on Kenya's 240V mains and through most of the low-voltage sags that follow a KPLC outage.
Where most Nairobi electronics shops sell unbranded chargers with no protection circuits, Mascom International stocks the genuine UGREEN unit with surge, overheating, overvoltage and short-circuit protection built in. Customers across Nairobi tell us their old no-name blocks ran hot or charged painfully slowly, and a branded PD charger is one of the cheapest upgrades they make. At KSh 1,400, the UGREEN X512 20W GaN Charger is a small spend that looks after a phone worth many times more. Walk in to test it on your own handset, or order on WhatsApp for pay-on-arrival delivery anywhere in Kenya.
Common Questions About the UGREEN X512 20W GaN Charger
How much is the UGREEN X512 20W GaN Charger in Kenya?
The UGREEN X512 20W GaN Charger costs KSh 1,400 brand new at Mascom International in Nairobi CBD. That price covers the charger unit with its UK 3-pin plug and a 6-month warranty against manufacturing defects. A USB-C cable is not included, so budget for one if your current cable is worn or frayed. Delivery is pay-on-arrival across all 47 counties. If you want more headroom for a tablet or a Samsung phone, the UGREEN X513 30W Fast Charger sits KSh 200 above it at KSh 1,600.
Does the UGREEN X512 20W GaN Charger fast charge an iPhone?
Yes, the UGREEN X512 20W GaN Charger fast charges iPhones through USB Power Delivery. Apple's fast-charge feature on iPhone 8 and later calls for a USB-C PD adapter rated 18W or higher, and 20W clears that bar. iPhones with a USB-C port need a USB-C to USB-C cable. Older iPhones with a Lightning port need a USB-C to Lightning cable, which Mascom International sells separately. iPads with USB-C also charge from it, just more slowly than from a 30W adapter.
Should I buy the UGREEN X512 20W GaN Charger or the UGREEN CD137 set with a Lightning cable?
Pick the UGREEN X512 20W GaN Charger if you already own a good USB-C cable or use a USB-C phone. Both deliver 20W, but the CD137 set at KSh 2,800 adds a 1-metre USB-C to Lightning cable in the box. That makes the set the easier choice for owners of older Lightning iPhones who need a matching cable today. The X512 costs KSh 1,400 less, its GaN design keeps the body small, and it leaves you free to pair any USB-C cable you like.
Is the UGREEN X512 20W GaN Charger safe during KPLC power cuts and surges?
The UGREEN X512 20W GaN Charger has surge, overheating, overvoltage and short-circuit protection, which matters when power returns with a spike after a KPLC outage. Its input accepts 100V to 240V, covering Kenya's 240V mains. The UK 3-pin plug fits standard Kenyan sockets with no adapter. In homes and shops where outages are frequent, plugging it into a surge-protected extension board adds a second safeguard. During heavy thunderstorms, unplugging chargers altogether is still the safest habit.
Who should buy the UGREEN X512 20W GaN Charger, and who should skip it?
Buy the UGREEN X512 20W GaN Charger if you need one reliable charger for a phone, earbuds or a smartwatch at the lowest price for a genuine branded unit. Skip it if you want to charge a laptop. Business laptops such as the HP EliteBook and Lenovo ThinkPad ship with 45W or 65W adapters and may charge at a crawl or show a warning on 20W. Laptop users should look at the UGREEN X553 65W Nexode S at KSh 3,800, which has two USB-C ports and one USB-A port.
Will the UGREEN X512 20W GaN Charger work with Samsung, Tecno and Redmi phones?
Yes, Samsung, Tecno, Infinix, Redmi and other Android phones with USB-C charge from the UGREEN X512 20W GaN Charger. Its PD 3.0 and Quick Charge 4.0+ support covers most Android handsets sold in Kenya. Samsung's 25W Super Fast Charging uses a protocol called PPS, which UGREEN does not list for this model, so a Galaxy phone charges at standard fast speed instead. Phones built around their maker's own high-wattage systems also charge at a normal USB-C rate.
Can I leave the UGREEN X512 20W GaN Charger plugged into my phone overnight?
Yes, leaving the UGREEN X512 20W GaN Charger connected overnight is fine for a modern phone. Phones stop drawing current once the battery is full, and the charger's overheating and overvoltage protection add another layer of safety. Most iPhones and Galaxy phones also have a battery-protection setting that pauses or caps charging around 80 to 85 percent. Keep the charger on a hard surface, not under a pillow, so heat can escape in warm Mombasa or Kisumu bedrooms.
How do I know the UGREEN X512 20W GaN Charger at Mascom International is genuine?
The UGREEN X512 20W GaN Charger at Mascom International is genuine UGREEN stock, brand new in sealed retail packaging. You can inspect the box, the printed ratings on the casing and the model code in person at our Kimathi Street shop before paying by cash or M-Pesa. Counterfeit chargers often feel lighter, carry blurry print and skip protection circuits entirely. Buying from a walk-in retailer with a physical address gives you someone to face if anything goes wrong.
Technical Specifications
Core Function and Power Output
- 20W top output from one USB-C port — enough to fast charge iPhones and most Android phones from a low battery.
- USB-C output profiles of 5V 3A, 9V 2.22A and 12V 1.67A — the charger and phone agree on the voltage that suits the battery.
- USB Power Delivery 3.0 with PD 2.0 support — the open charging standard that iPhones, Pixels and most new Android phones use for fast charging.
- Quick Charge 4.0+, with QC 3.0 and 2.0 support — Qualcomm's fast-charge system, found on many Android phones that run Snapdragon chips.
- Huawei FCP and SCP plus BC 1.2 — older Huawei phones and basic USB gadgets such as earbuds and power banks charge at a sensible rate.
- Gallium nitride (GaN) parts — they waste less energy as heat, which lets UGREEN fit 20W into a smaller body than older silicon chargers.
Compatibility With Phones and Gadgets
- iPhone 8 and later — fast charges through a USB-C to Lightning or USB-C to USB-C cable, depending on the phone's port.
- Samsung Galaxy phones and tablets — charge through Power Delivery at standard fast speed; the 25W Super Fast mode needs PPS, which this model does not list.
- Tecno, Infinix, Oppo, Redmi and Vivo phones — charge reliably over USB-C, though brand-specific high-wattage modes still need the maker's own charger.
- AirPods, Galaxy Buds, smartwatches and fitness bands — the charger only sends as much power as each small device asks for, so nothing is overloaded.
- iPads and Android tablets with USB-C — charge steadily, though a 30W adapter refills a large tablet battery faster than this one.
- Power banks with a USB-C input — a 20W source refills most mid-size power banks overnight, ready for the next day out.
Build and Safety Protection
- UK 3-pin plug, also called Type G — fits standard British-style wall sockets directly, with no loose travel adapter in between.
- Input rated 100V to 240V at 50 or 60Hz — runs on 240V mains and works abroad with the right plug adapter.
- Surge protection — guards your phone against the spike that can arrive when mains power returns after a blackout.
- Overheating protection — the charger holds back when its temperature climbs, useful in hot rooms and on sunny shop counters.
- Overvoltage and short-circuit protection — stops a faulty cable or damaged port from passing dangerous current into your phone.
- Plastic housing in black — light enough for a bag pocket and easy to wipe clean of dust and fingerprints.
Inclusions and Support
- The X512 charger unit with its fixed UK 3-pin plug — sealed in UGREEN retail packaging, ready to plug in.
- No cable in the box — pair it with a USB-C to USB-C or USB-C to Lightning cable, sold separately at Mascom International.
- 6-month Mascom International warranty — covers manufacturing defects, with claims handled at our Nairobi CBD service desk.
- In-store testing — plug it into your own phone at our counter and check the charging status on screen before paying.
- Pay-on-arrival delivery — inspect the sealed box at your door before you hand over any money.
